Croy represented Western Province at the 2004 Under-18 Craven Week tournament. This led to his inclusion in the South Africa Under-19 squad for the Under 19 Rugby World Championship in 2005. Further appearances for Western Province followed at Under-19 level in 2005 and at Under-21 level at 2006 and 2007.

Croy then joined George-based side the SWD Eagles during the 2008 Currie Cup First Division season, making four appearances. He was 5th top scorer in the 2009 Vodacom Cup, scoring 94 points.[3] A further 48 points in the 2009 Currie Cup First Division followed to help them finish second in the league, but they failed to win promotion, despite him accumulating the highest individual tally in the play-off games, scoring 23 points.[4]
In 2010, Croy then moved to Premier Division side the Pumas, whom he regularly represented over the next two seasons.
Croy made the move back to the Western Cape in 2012, linking up with the Boland Cavaliers.
